Cardiovascular diseases are responsible for nearly half of cause of deaths in the industrial countries. The prevalence of physical inactivity, one of the cardiac risk factors, is dramatically increasing. On the other hand, the benefit of activity is well documented in several studies, but the form, intensity and frequency are controversially discussed. Obviously, the status of physical fitness plays an important role as a predictor of cardiovascular diseases. To improve fitness, training has to be relatively intensive. On the other hand moderate physical activities, incl. daily activities seem to be beneficial  especially for beginners. Physical activity can trigger cardiovascular events, but active persons are less concerned than inactive.
